I need help to match a url that matches only if

• the path matches exactly /gummybear/ or /gummybear (case sensetive)
• the protocol is http or https
• the domain/host/port/hash can be anything

the regex should not match if

• the path is /gummybear/foobar
• it contains search parameters such as ?query=string

So far i got this:

/^http[s]?:\/\/?[^\/\s]+\/gummybear[\/]?/

examples it should be true for

:81/gummybear/

:81/gummybear#/foobar/?search=params
:81/gummybear
:81/gummybear/#/exaple/1234/

examples that it should be false for

:81/foo/gummybear/
:81/guMmybear/
:81/gummybear.html

file://example:81/gummybear#/foobar/?search=params
:81/gummybear?search=apple#lol
:81/#/gummybear/
:81/dir/dir.2/index.htm?q1=0&&test1&test2=value#top

• What are the differences between your "should match" https://example.:81/gummybear/#/exaple/1234/ and your "shouldn't match" the path is /gummybear/foobar ? – Federico Piazza Commented Oct 13, 2015 at 23:49
• @FedericoPiazza it matches another sub directory – Endless Commented Oct 14, 2015 at 0:04

For your specific needs, I can e up with this regex:

^https?://[^/]+/gummybear(?:/?|/?#.*)$

Working demo

I haven't escaped slashes to make it more readable, but for javascript you can use:

^https?:\/\/[^\/]+\/gummybear(?:\/?|\/?#.*)$
